Token: A token represents a common sequence of characters. The number of tokens used for each English character may vary. For example, a single character like “antidisestablishmentarianism” might be broken down into several tokens, while a short and common phrase like “word” might use just one token. Generally speaking, for a typical English text, 1 token is roughly equivalent to 3-4 English characters. The exact number of tokens generated by each call can be obtained through the Token Calculation API.

Billing Logic

Model inference APIs bill both Input and Output based on usage. If you upload and extract content from a document and then pass the extracted content as Input to the model, the document content will also be billed based on usage. File-related APIs (file content extraction and file storage) are temporarily free: if you only upload and extract a document, the file APIs themselves incur no charges. Explanation: Prices exclude applicable taxes. Specific tax obligations are subject to local tax regulations and will be calculated at checkout based on your jurisdiction.

Model Pricing

Here, 1M = 1,000,000. The prices in the table represent the cost per 1M tokens consumed.
